most of the newer drones are fairly tough. i've crashed them into bus seats (many, many times) and stairwells and usually manage to get them back up and running without having to retrieve it.
you need a vo/spotter if you're flying an fpv drone, solo flying is illegal in the us. the faa requires you to have a line of sight with the drone while flying.
if you get motion sickness, you'll probably get sick with an fpv drone. if you don't get motion sickness, you still might get sick using and fpv drone. don't use someone else's goggles, there's a good chance there's been some sick on them. the avata looks like a cinewhoop drone. not sure if it is or if it just looks like one, but they're very maneuverable drones and the chance of getting sick goes up.
i doubt it'll get much use with first responders. the enterprise drones with flir capabilities and the longer battery life are usually the top choice. you really don't want to wear goggles that cover your vision at a scene, especially if things go south and you need to quickly move your staging area or cp back. our drone response vehicle is a heavily customized hazmat truck. 3 pilots can fly simultaneously, but we usually do a maximum of 2 drones with a police chopper overhead. there's large screen tvs inside the truck and on outside panels so anyone nearby who wants to see can gather and watch. or we can stream to an on scene command post or operations center using airdata.
